The EAS is power-cycled during normal communications operations. When the EAs is power-cycled, the BECM will beep and display the “slow 35mph Max” message. This is normal and does not indicate a stored EAS fault.

No. This is not possible. the voltages and the messaging protocol for USB serial ports are extremely different from a RS232 serial port. The two are simply not compatible. You need to purchase a USB to Serial Adapter that will interface and translate between the two protocols.   Would it be possible for me to…

If your laptop or computer does not have a RS232 serial port then you can still use the software. You will need to purchase a “USB to Serial Adapter”. These are inexpensive devices that emulate a RS232 DB9 male serial port. Typical cost is usually from 10-15 USD. More expensive models are avalaible but will…

This is a comm port setting problem. Refer to the “What Comm Port Do I Use” section to determine the correct comm port number. This is the loopback problem. The queries for the stored heights are being echoed back in to the Rx buffer. All data displayed in the EASunlock software is false when you are…

Generally, you will never have to modify the delay sliders. The following circumstances necessitate adjusting the sliders. If you are completely unable to get a value of FF back from the EAS, then adjusting the Idle delay to a quicker setting can some times help. If you are constantly getting 255 values when trying to…

The text boxes inside the EASunlock software hold values that are returned from the EAS. A specific rule is that the value of 255 should never show up in these boxes. When you see a value of 255 in the EASfaults or EAScalibrate application this is incorrect. To fix the situation, simply try to read…

This is also caused by an incorrect comm port setting. Refer to the “What Comm Port Do I Use” section to determine the correct comm port number. Turns out that some laptops have a comm port that echos everything back into the Rx buffer. I have no idea why or how. With this loopback port,…

This is usually caused by an incorrect comm port setting. Refer to the “What Comm Port Do I Use” section to determine the correct comm port number. Also, it has been reported that some really super cheap USB to Serial Adapters simply do not work. If your USB to serial adapter is suspect, I would…

After you are certain of the Comm port number, you are ready to Initialize. When you press the Initialize button, a series of values will be sent to the EAS. The EAS will then be power-cycled. After the unit is power-cycled, full communication will begin. When synchronized, the EAS will respond with a stream of…

When you open any of the EAS software applications, you will typically get a comm port error. This is normal. The application is set up to use Comm port 1 by default. If you do not have a comm port 1 then it will throw the error. With the EAS application running, choose the drop…
